Appearance
The Pellaea Leucomelas fern has small, delicate fronds that are a light green color. The fronds are bipinnate, meaning that they are divided into two sets of pinnae, with each pinnae further divided into smaller leaflets. The leaflets are oblong in shape and have a slightly wavy edge. The fern’s spores are produced on the underside of the fronds, in clusters called sori. The sori are covered by a thin membrane called an indusium.

Pellaea Leucomelas ferns prefer well-draining soil and partial shade. They require regular watering, but the soil should be allowed to dry out slightly between waterings to prevent root rot. Fertilizer can be applied during the growing season to encourage healthy growth. The fern is hardy in USDA zones 8 to 10.
